coiaims.

Thisinvention relates generally to diapers and more particularly todiapers of the pinless type.

An object of the invention is to provide an improved diaperincorporating fastening means by which a diaper can be put on andsecurely fastened in place without the use of pins or other separatefasteners.

Another object of the invention is to provide a pinless diaper havingfastening means adjacent its opposite edges by which the diaper can befitted snugly to a baby without the use of strings orother additionalfasteners.

A further object of the invention is to provide a diaper incorporatingfastening means which is adjustable to fit a baby of any size.

An additional object of the invention is to provide a pinless diaper ofsuch shape that it requires no initial folding and is ready forimmediate use.

Another object of the invention is to provide a pinless diaper ofsubstantially hour-glass shape incorporating fastening means by whichthe ends of the diaper are secured in place whereby uncomfortablebulkiness is avoided and snug fit assured, I

Another object of the invention is to provide a diaper incorporatingfastening means so arranged that no metal or other relatively hardsubstance can touch a babys body. 7

A further object of the invention is to provide a pinless diaper whichis highly absorbent and long wearing.

Other objects and advantages of the invention will appear hereinafter inthe detailed description, be particularly pointed out in the appendedclaims and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of a diaper embodying the presentinvention, the parts of the diaper being shown as applied to a baby, butwith one side unsecured to illustrate certain of the details ofconstruction.

Figure 2 is a vertical sectional view on an enlarged scale taken alongthe lines 22 of Figure 1.

Figure 3 is a fragmental plan viewon an enlarged scale of one corner ofthe diaper showing a modified form of securing means.

Figure 4 is a vertical sectional view on an enlarged scale taken alongthe lines 4-4 of Figure 3.

Figure 5 is a horizontal sectional view on an enlarged scale taken alongthe lines 55 of Figure 3, and

Figure 6 is a plan view of the diaper on a reduced scale.

Referring now in detail to the drawings in which like referencecharacters designate like parts, the diaper, designated generally as l,preferably is multi-layered and comprises inner and outer sheets, 2 and-3, respectively. To avoid chafing a babys skin, these sheets may bestitched or otherwise secured together, with their edges tucked orfolded in, as shown in Figure 2, so that the edge of the diaper issmooth.

As shown in Figure 6, the diaper has an elongated body 4 of somewhathour-glass shape and its end or front and rear waistband portions, 5 and6, respectively, are of relatively greater width than the intermediateor crotch portion '1.

For securing or fastening the diaper in place, there are provided oneach of the waistbands 5 and 6, adjacent the upper and lower edges ofthe diaper but on opposite sides, strips, tapes or bands 8 and 9,respectively, which are sewn or otherwise secured to the diaper. Thesestrips desirably extend substantially to the outer edges of theirrespective waistbands. Adjacent and preferably underlying the outerendof each of the strips 8 and 9 is ahook or other fastener or securingelement ID of metal or other suitable material, there thus being afastening element in each of the four corners of the diaper. To avoidpossible contact between the hooks and a babys skin the hooks arepreferably confined within the edges of the diaper, so as to beseparated from the skin by one or more layers of the diaper. On eachwaistband inwardly of the hooks are positioned the securing means orfastening elements for engaging, interlocking, or mating with the pair"-of hooks on the opposite waistband.

While the corner fasteners and the mating elements inwardly of the endsof the strips by which the opposite ends of the diaper are fastened orsecured may be of several forms, only two forms of mating fasteners havebeen illustrated, each of which is adapted to receive a hook. Thefirstof these mating fasteners appears in Figures 1, 2 and 6. As there shown,a plurality of spaced eyelets or openings H, havingreinforced edges, areformed in the strips inwardly of their outer ends. The other form, shownin Figure 5, comprises a pleated strip having spaced, inwardly directedpleats l2 for en gaging the hooks. As preferred with either the pleatedor reinforced eyelet type, the strips may be attached to the outside ofthe diaper, as in Figure 1, or inserted between its layers through arectangular slot l3 formed in the sheet corresponding to the face orengaging surface of each strip. In the latter case, each slot ispreferably of less dimensions than its associated strip to enable theedges of the sheet defining the slot to partly overlap and be stitchedto the face of the strip, thus reinforcing the latter.

As previouslymentionedand as shown in Figure'6, the diaper is preferablyof substantially hour-glass form or configuration with its least widthapproximately midway between its ends.

So formed, the intermediate portion of the diaper will conform to thecorresponding portion of a baby to whom the diaper is applied,regardless of the babys size, without uncomfortable folds or extra bulk.The widths of the waistbands 4 and 5 are relatively greater andpreferably of such combined dimension or circumference as to encirclethe waist of any baby, at least up to the training stage.

The diaper may be applied in the usual manner by placing the rearwaistband 3 against the back of the baby and bringing or folding thefront waistband up over its stomach to encircle the babys waist. Theadjacent sides of the waistbands are next brought together with theircorners overlapping, the corners of the front waistband underlying therear waistband in the illustrated embodiments. To fasten or secure thediaper in place it is then only necessary to engage or interlock thehooks i (l on each waistband with the confronting or contiguous eyelets,pleats or other fastening elements ii and IE on the other or oppositewaistband. By this means the four corners of the diaper are secured orheld in place and all possible bulking or underfolding as a result ofsubsequent activity of the baby avoided. Accordingly, it is onlynecessary to provide sufficient openings, whether in the form of eyeletsor pleats, inwardly of either side of each waistband to enable thediaper to be fitted snugly to any size of baby with all of its cornerssecured.

It will be apparent from the foregoing detailed description that therehas been provided an improved diaper of the pinless type which fitssnug- 1y without prefolding, can be applied to a baby of any size, andall corners of which can be secured in place. It should be understoodthat the described and disclosed embodiments are merely exemplary of theinvention and that all modifications are intended to be included whichdo not depart either from the spirit of the invention or the scope ofthe appended claims.

We claim:
